Similarities in anatomy can help indicate evolutionarily relationships with similar structures are not always the result of revolutionary relationship Justify this statement with examples

Analogy or Homoplasy

Explanation:

Analogy:  also called homoplasy, when similar characteristics originated due to the environmental conditions, and not by the result of  close evolutionary relationship.

Example: insects wings like bats and birds, but their embryonic origin and wing structure differ.  

Another thing is that:  by the use of similar environmental conditions, unrelated organisms may appear very similar due to common adaptations
